Worked great in my Fender Super Champ X2

Might sound good in an overly bright fender amp that you want to really tone down

and i can get more classic fender tones than I ever could with the stock tubes

I was killing the little pre amp before, now I only need to turn it to one fourth of the power and my solid state Fender Mustang sounds like an over driven Black Face .Fender amp of the past
